HYDROCARBON-SPRAYING DEVICE FOR GASOLENE-ENGINES.

SPECIFICATION formingpart of Letters Patent No. 677,767, dated July 2,1901.

Application filed June 14, 1900.

To all whom, it 11mg concern..-

Be it known that I, THOMAS E. JEFFERY, a citizen of the United States,residing at Ohicago, county of Cook, State of Illinois, have inventedcertain new and useful Improvements in Hydrocarbon-Spraying Devices forGasolene-Engines, of which the following is a specification, referencebeing had to the accompanying drawings, forming a part thereof.

In the drawings, Figure 1 is an end elevation of a portion of agasolene-engine having my spraying device connected with it, a portionof thecase of the latter being broken away to show the interiorstructure. Fig. 2 is a section at the line 2 20:1 Fig. 1. Fig. 3 is adetail section at the line 3 3 on Fig. 2. Fig. 4 is a similar View toFig. 2, showing a modified form of the spraying device. Fig. 5 is a Viewsimilar to Fig. 2, showing another modified form of the spraying device.Fig. 6 is a cross-section of a third modified form of spraying, device.Fig. 7 is a perspective view of the mouthpiece.

I will describe first the particular form shown in Fig. 1. A is achamber which is supplied withliquid hydrocarbon to any desired depth,as to the level a a. B is a skeleton wheel, disk, or spider fixed on ashaft b, which is journaled in one wall of the chamher A and protrudingout of the same, having on its outer end a pinion B, which meshes with agear-wheel B which is rotated in uniform time relation with the engineby means of any suitable train extending to the engines maincrank-shaft. A portion of this train, as illustrated, comprises thecounter-shaft d, having a beveled gear 01, meshing with a beveled gear Don the upright shaft D, which carries the worm D meshing with anddriving said gear-wheel B O is a capillary screen, of woven wire of finemesh or other fabric adapted to hold liquid in its meshes. This screenis stretched over the face of the wheel or spider B, which has amarginal flange 1), adapted to afford attachment for the screen at theperiphery of the latter. On the wall A of the chamber A which the screen0 faces there is formed an exterior boss A2 which ishollow, its cavityconstituting a small chamber or passage opening into the cavity of thechamber A.

Said boss A has a lateral opening A, thread- Serial No. 20,244- (Nomodel.)

ed to afford connection for a pipe F, which leads to theengine-cylinder, being suitably branched, as seen at F F, to reach thetwo cylinders of a double-cylinder engine. G is a mouthpiece located atthe mouth or opening of the cavity of the boss A into the chamber A. Itconsists of a disk having spiderarms G G, converging to the stem G whichextends at right angles to the plan eof the disk and constitutes a shaftby which the disk is mounted and operated, said shaft extending outthrough the boss A in which a journalhearing a is provided for itconcentric with the opening of the cavity ofthe boss into the chamber A.Said opening is circular and affords a seat or j ournal-bearing for themouth piece, which has the flange or annular boss G concentric with itsstem, adapted to seat in said opening, the converging spider-arms Gbeing rooted in and extending conver ently from said flange. Outside theboss A the stem G2 is provided with a suitable stop-collar g which isadjusted against the head of the boss, so as to hold the mouthpiece inits seat at the mouth .of the boss, said col-' lar having a handle 9which serves also as an index-finger, denoting the position of the mouthor aperture 9, which is formed in the mouthpiece G. This aperture 9 isoblong and preferably elliptical,so that as the mouthpiece is rotated bymeans of the handle 9 the dimension of said aperture standing radial tothe axis of the rotating screen is shifted, changing gradually from theshortest dimension at the lesser axis of the ellipse to the longestdimension at the greater 'axis of the ellipse, thus gradually changingthe width of the annular area or zone of the screen from whoseinterstices the liquid which is carried thereby is sucked or forced asthe screen revolves past said aperture of the mouthpiece. It will beunderstood that suction is produced through the pipe F by reason of theaction of the piston in the engine cylinder to which the pipe isconnected, tending to draw in air to said cylinder, and the mouthpiecestanding in close proximity to the screen, the mouth or aperture throughsaid mouthpiece being closed by the screen so long as the apertures ofthe screen are filled with the liquid, such suction. tends to draw inair through the apertures of the screen, thereby extracting the liquidfrom the same and discharging it in a spray in the air supplied to theengines cylinder, as described. The operator by adjusting the mouthpieceis thus able to vary the amount of spray which is taken in at eachimpulse or sucking action, so as to vary the richness of the charge ofmixed air and hydrocarbon which enters the explosion-chamber. The extentof the aperture in the mouthpiece in the direction in which the screenrotates does not materially affect the amount of hydrocarbon which istaken in at each impulse, because practically the apertures of thecapillary screen are emptied of their liquid as fast as they pass theedge of the aperture in the mouthpiece, and the amount taken intherefore is determined by the speed of the rotation of the screenrelative to the engines action and the extent of the aperture in adirection radial to the axis of rotation of the screen. The wheel whichcarries the screen being geared to the main engine crank-shaft,operating in uniform time relation thereto, being faster when the engineis running at high speed and slower when the speed of the engine isless, but making always the same travel for each complete rotation ofthe crankshaft, each discharge of hydrocarbon corresponds to the samenumber of degrees of rotation of the screen, and the discharges vary,therefore, as the adjustment of the mouthpiece changes the position ofthe mouth, causing a different dimension of such month to standtransverse to the direction of movement of the screen in its rotationpast the mouth.

I do not limit myself to the screen in the form of a disk which rotatesabout its axis. It may be conical in form, as shown in Fig. 4, in whichP is the wheel or spider and P is the screen, or it may be cylindricalin form, as shown in Fig. 5, in which R is the spider and R is thescreen, or it may be in the form of an endless belt 0, passing aroundtwo pulleys M and N, as shown in Fig. 6. In each form a suitablearrangement of mouthpiece will be adopted, so that the month shall faceand stand as close as may be to the screen and be adjustable about anaxis at right angles to the path of the screen at the point at which themouthpiece faces the latter.

I do not limit myself to the particular form of aperture or mouth in themouthpiece shown, though it is the most expedient to construct andadjust and for that reason is specifically claimed; but the essentialfeature of this aperture is that it has different dimensions indifferent directions, so as to be adjustable to change the dimensionwhich extends transversely to the direction of movement of the screenpast it. I do not limit myself, however, strictly to making the screenmovable. It is only essential that there shall be relative movement asbetween the screen and the mouthpiece. Inasmuch, however, as it is moreconvenient and yields the more compact structure to make the screen themovable element,'I have so shown it and claim this structurespecifically.
